You want to inspect the management engine not replace it.

The management engine does do useful stuff the issue is that we don't know what else it does too.

You meant ME? Maybe, they do refer the use of HAP mode on the linked article (Goldmont's Red Unlock) BUT I think the ME platform is required for useful, needed things along the unneeded ones, so I think in the end, you always need a subset of Intel ME working.
